More particularly, it relates to a press for coils of steel rod from 34 inch to 2 inch diameter which are compacted and strapped to facilitate handling, storage, shipment and annealing thereof.

Rod coil presses available heretofore have been subject to numerous limitations and objections. Thus prior presses have been unduly heavy, complicated, slow to operate, difficult to lubricate and maintain, and usually have been sensitive to wild loops or strands which interfere with closure of strap tracks or guides and to various other malfunctions and to damage thereof. Prior machines also have been characterized by limited capacity as to coil length and weight and by difficulty of maintaining a predetermined inner coil diameter.

it is a primary object of this invention to provide a device which overcomes or eliminates the problems and limitations of prior devices and which is subject to minimum requirements for lubrication and for operating maintenance.

A further object is to provide a device of this character having a novel construction of a coil carrier or horn.

A further object is to provide a device of this character having a coil carrier with novel means for sizing the interior diameter of the coil as it is being compacted.

A further object is to provide a device of this character having a novel arrangement of coil carrier and compactor which interfit in a manner to accommodate rapid and convenient application and tensioning of straps utilized to secure the coil in compacted condition.

A further object is to provide a device of this character having a coil carrier rotatable between an operative position aligned with a compactor and angularly displaced loading and unloading positions, and having strap guide means of novel character.

A further object is to provide a device of this character having a coil carrier or horn of substantially Y-shape in cross section and shiftable between retracted loading position and extended coil-diameter-controlling dimension, and which accommodates strapping guides and also accommodates the use of ram trucks, crane hooks or other carriers to rapidly and easily load a loose coil upon the carrier and to unload a compacted coil from the device.

A further object is to provide a device of this character having a novel, efficient and rugged construction and a novel combination and cooperating relation between coil carrying means, compacting means and strapping means.

My improved coil compacting device comprises a coil carrier or horn rotatably mounted upon a frame to swing to and from loading and unloading positions at an angle to the frame and a compacting position aligned with the frame. The coil carrier is of Y-shape in cross section, having one leg of the Y projecting downwardly and adjustable in length between an extended coil diameter-control position and a retracted release position. A compactor shiftable on the frame cooperates with the coil carrier to compact a rod coil on the carrier. The rotatable coil carrier also carries strap guides and cooperates with guides upon the compactor to accommodate banding of the coil in desired compacted dimensions or size by a plurality of metal bands or straps.

Referring to the drawings which illustrate the preferred embodiment of the invention, the numeral 20 designates an elongated rigid frame or base which may be of any suitable construction, and which preferably includes parallel longitudinal ways or tracks 22.

A coil carrier assembly 24 is mounted at one end of the frame 20 to rotate upon a vertical axis. As here shown, a base plate 26 secured in horizontal position to the top of the frame 20 at the end thereof supports an upright tubular member 28 for rotation about its axis. Suitable bearings (not shown) at:- commodate rotation of member 28 upon plate 26. A top plate 30 is secured on the upper end of tubular member 28 and projects forwardly and laterally therefrom. A vertical face plate 32 is secured to the forward or inner end of the top plate 30 and is reinforced by suitable gusset plates 34 secured thereto and to the top plate 30. Face plate 32 is preferably interrupted by a cutaway 36 at the top center portion thereof, and by a pair of angularly downwardly extending side cut-aways 38, as best seen in FIGS. 6 and 9. Uprights 40 are secured to plate 30 and mount a horizontal member 42 which includes a disk or plate 44 upon which a turntable 46 is journaled by any suitable bearing means.

An overhead or elevated structure extends longitudinally of the frame 20 in spaced relation thereabove and horizontally. This overhead structure includes cross members 48 which are secured to the disk or turntable 46. Spaced parallel horizontal longitudinal rail members 50 are connected to the ends of cross members 48. The opposite ends of rail members 50 are supported by uprights 52 located at the opposite end of the device, and here shown as supported upon a tank or liquid reservoir 54 carried by base 20 and forming a part of a hydraulic system employed in the device.

An elongated cantilevered coil carrier or horn 56 is carried by and projects horizontally forwardly or inwardly from the face plate 32. The coil carrier 56 includes an upper rigid horizontal unit of V-section providing a pair of upwardly diverging elongated horizontal arms, flanges or plates 58. A pair of laterally spaced elongated vertical guide plates 60 depend from the upper arms 58 centrally thereof and extend longitudinally the full length of the arms 58. Both guide plates 60 have a plurality or set of similar parallel elongated inclined slots 62 formed therein at spaced intervals along the length thereof, and also are provided adjacent their free ends with a vertical slot 64.

A sizing plate 66 is positioned between and extends lengthwise of guide plates 60. Sizing plate 66 has a plurality of parallel inclined slots 68 therein complementary to but inclined oppositely relative to the slots 62 in plates 60. Sizing plate 66 also carries a cross shaft projecting therefrom and mounting rollers 70 positioned in the vertical slots 64 of guide plates 60. An elongated yoke member 72 having a pair of elongated parallel horizontal yoke arms straddles the guide plates 60. Yoke member 72 carries a plurality of longitudinally spaced cross shafts which mount rollers 74 adapted to roll in the inclined slots 62 and 68, as seen in FIGS. I0, 11 and 13. Yoke 72 passes freely through an opening in the face plate 32 in a vertical passage thereof (not shown). Yoke 72 is provided with a yoke head 76 at its outer end, to which is pivotally connected at 78 the ram or piston rod 80 of a double-acting fluid pressure extensible and retractable member or cylinder 82. The opposite end of member 82 is pivoted at 84 to a bracket 86 secured to the tubular or upright member 28.

A pair of plates 88 extend lengthwise of the coil carrier 56 below the upper arms or plates 58 thereof, being welded thereto and to the guide plates 60 to extend in laterally downwardly inclined divergent relation from the upper margins of said guide plates 60. Reinforcing plates 90 extend between the outer margins of the plates 88 and the outer portions of the upper arms or plates 58, as best seen in FIGS. 6 and 9. Longitudinal channel-forming members 92 are secured to the under sides of the downwardly divergent plates 88 to provide strap guides. Longitudinal ribs 94 are preferably provided on the upper faces of the V defined by the arms 58 to provide an upper strap guide.

Coil carrier assembly 24 also includes an upper curved strap guide 96 fixedly carried by plate 30 and bent through approximately 180 to preferably terminate at a level adjacent the level of the lower portion of the longitudinal rails 50. Laterally downwardly inclined plates 98 project below plate 30 rearwardly or outwardly of face plate 32 and are provided with curved track guide surfaces 100 extending substantially 180. The strap guides may be of any character found suitable, and one embodiment which may be utilized is illustrated in FIG. 8 wherein the curved guide member 96 is provided with a plurality of transverse passages 102 at spaced intervals along its length, each receiving a coil spring 104 which has an enlarged head or member 106 at each end bearing against the outer surface of a side guide plate 108. Plates 108 are pressed against the sides of guide 96 by the spring. Projecting beyond the curved edge of guide 96 is an inturned marginal portion 110 adapted to releasably retain a metal strap member 112.

Any suitable means may be employed to swing the coil carrier assembly 24 between the operative position thereof aligned with the frame, as illustrated in full lines in FIG. 4, and loading and unloading positions thereof, as illustrated in dotted lines in FIG. 4. As here illustrated, an arm 114 is secured to and projects laterally from the upright tubular member 28 and is pivotally connected to the piston rod 1 16 of a fluid pressure member whose cylinder 118 is pivotally connected to a bracket 120 secured to the frame 20 spaced from the tubular member 28.

A compactor assembly 122 is mounted to traverse the frame 20 and is supported upon longitudinal members 124 which journal upper rollers 126 and lower rollers 128 at opposite ends thereof. Rollers 126, 128 traverse the ways or tracks 22 of the frame. Members 124 support a part 1300 of a leading compactor plate and a trailing compactor plate 132 extending vertically and transversely. Plates 130, 132 are spaced apart and interconnected by longitudinal compactor frame members 134. The leading compactor plate 130 is formed in three segments, 1300, 130b and 130C, as best seen in FIG. 7, which are supported by frame parts 134 in spaced relation to provide gaps located similarly to the side cut-aways 38 of the face plate 32 of the coil carrier. Plate 132 is preferably of a configuration similar to that of plate 32 of the coil carrier assembly and provides means in association with compactor frame members 134 to position the leading compactor plate segments 1300, 1311b and 1311c. Each of the leading compactor plate segments 130a, 1301; and 130: is provided with a notch 136, which notches are adapted to receive therein with clearance the plates 58 and 66 of the coil carrier arm or horn.

A reinforcing end structure 138 is secured to trailing plate 132 and to longitudinal members 124 and provides means for connection to the compactor assembly 122 of a ram or piston rod 140 of a double-acting fluid-pressure member whose cylinder 142 is suitably anchored to fixed parts of the apparatus, and which is associated with suitable fluid-pressure generating means, such as a motor-pump set 144, in a fluidpressure circuit which may also include the reservoir 54.

Compactor assembly 122 has associated therewith an upper central strap guide 146 and a pair of downwardly laterally inclined strap guides 148 which respectively complement the strap guides 96 and of the coil carrier assembly, and are aligned or registered therewith.

A strapping assembly is mounted on the frame rails 50 to traverse the same. The strapping assembly is provided with a rigid frame, including spaced elongated transverse frame members 152 and spaced longitudinal frame members 154 rigidly secured together. Longitudinal frame members extend alongside the rails 50 and each preferably carries a set of upper and lower rollers 156 at each end thereof. The rollers 156 of each set engage the upper and lower surfaces of the flanges or tracks of the rail member 50 to guide travel of the strapping assembly along the rails. Cross members 158 span and are secured to the rails 50 at the ends thereof adjacent the supports 52 and serve to mount a double-acting fluid-pressure cylinder 160 from which projects a piston rod 162 secured to a transverse frame member 152 of the strapping assembly.

The frame of the strapping assembly includes vertical guides 164 carried by and projecting upwardly from the transverse frame members 152 centrally thereof and equispaced from rails 50 and compactor plate segments 130a and 1301:. A strapping mechanism 168 is secured to a traveling assembly member 166 which is vertically shiftable on the guides 164. As here illustrated, the position of the strapping mechanism 168 may be controlled by a double-acting fluid-pressure cylinderpiston unit 170 having one end thereof connected to the traveling assembly member 166 and its opposite end secured to a cross member (not shown) connecting the transverse members 152.

At each end of the strapping assembly is journaled a transverse rotatable bar 172. A depending arm structure 174 is carried by each bar 172, and as here shown is comprised of two downwardly converging rigid arms which are interconnected by a cross member 176 adjacent their upper ends and are connected at their lower ends. A pair of double-acting fluid-pressure cylinder-piston units 178 each have one end thereof pivotally connected to a longitudinal frame member 154 and the opposite end thereof connected to a cross member 176 of a depending arm structure 174, thus providing means for controlling the pivoted positions of the two depending arm structures 174. Each depending arm structure 174 mounts a strapping mechanism 180 at its lower end in a position adjacent to a strapping guide 148.

A device of this character may be designed to compact coils having dimensions of the following order: a maximum weight of 8,000 pounds, a nominal inner diameter of 36 inches, a nominal outer diameter of 56 inches, a maximum uncompacted coil length of 54 inches and a minimum compacted coil length of 9 inches. The compacting and sizing pressures are preferably exerted by hydraulic cylinders which may have a maximum compacting pressure in the order of 70,000 pounds and a maximum radial sizing effort or pressure in the order of I 8,000 pounds.

in the construction shown, the compacted coil 182 is retained by three metal straps or bands 112 displaced approximately 120 from one another and each passing through the eye of the coil and thence around the coil. It will be understood that, although the machine illustrated is designed to apply three metal straps to the coil, the construction may be altered to apply two straps or four straps if desired. The comnacting and strapping of the coil convert the coil from an innerently weak and unstable unit subject to tangling with itself or with anything it touches to a unit which may be handled, stored, shipped and annealed, as incident to preparation for subsequent processing of the coiled rod, with minimum difficulty.

The operation of the machine is as follows: With the compactor assembly 122 and the strapping assembly 150 retracted to positions clear of the free end of the coil carrier or horn $6 and with the sizing plate 66 of the horn retracted to the position shown in H6. and in full lines in FIG. 9, the coil carrier assembly 24 is swung to an angular position relative to the frame by actuation of the cylinder 1 18, for example, to the position illustrated in FIG. 2. The horn 56 is preferably swung to a position extending from 45 to 90 relative to the frame 20, so that the free end thereof will be clear of the frame 20. Thus means for loading a loose coil 182a may approach the machine to a loading position. As illustrated in FIG. 2, the loading means may comprise a lift truck 184 having a ram 186 projecting forwardly. therefrom and providing means to suspend the loose coil l82a for transport to the machine. The Y-shaped cross section of the coil carrier or horn 56 readily accommodates the ram 186 of the truck in the space above and between the upper arms 58 of the coil carrier while the loose coil 182a is advanced to a position encircling the coil carrier. When the coil 182a encircles the carrier, the ram 186 may be lowered to transfer support of the coil to the coil carrier 56, whereupon the coil loading means can be withdrawn to a position clear of the device.

After the loose coil 1820 is loaded upon the coil carrier 56 of the device, the coil carrier assembly 24 is swung by operation of fluid-pressure unit 1 18 to a position in which carrier 56 is parallel to the frame 20 and aligned and registering with the notches 136 in the compactor unit 122. After this alignment is efi'ected, the fluid-pressure cylinder 142 is activated to move the compactor assembly 122 toward and into interfitting relation with the coil carrier 56, so that the ends of the loose coil 1820 are engaged by face plate 32 and the leading compactor plate segments 1300, 130k and 130C. When a predetermined amount of pressure has been applied to the coil, the fluid-pressure member 82 is activated to extend downwardly the sizing plate 66 of the coil carrier, as to the position illustrated in FIG. 11. With the downward extension of the sizing plate 66, the maintenance of a minimum desired diameter of the coil is assured, inasmuch as the interior opening or eye of the coil 182 will then be engaged at substantially equispaced points by the free edges of the upper arms 58 of the carrier and the bottom edge of the sizing plate 66. The application of compacting pressure by the compactor assembly 122 activated by the fluid-pressure member 142 continues until the desired pressure has been applied and the desired compaction effected.

As the compactor is advanced, the strapping assembly 150 preferably is advanced along rails 50 toward the coil by fluidpressure member 160, preferably at a faster rate than the compactor advances, and the strapping mechanisms 168 and 180 are actuated. It will be observed that, since the strap guides 146 and M8 advance with the compactor assembly 122, they assume operative positions relative to the strap guides 96 and I00 of the coil carrier assembly as compacting of the coil occurs. Thus the strap guides form guide paths for metal strapping fed by the strapping mechanisms 168 and 180. The respective guide paths include the channels 92 at the sides of the coil carrier and the channel defined between guides 96 at the central top portion of the coil carrier. Actuation of the strapping mechanisms 168 and 180 can occur simultaneously in the manner well understood in the art, and entails feeding of a strap 2 from each strapping mechanism to pass through the eye of the coil I82 and exteriorly around the coil, followed by tensioning of the strap, sealing thereof, cutting of the strap outwardly of the sealed part thereof and release. The operations of tensioning, sealing, cutting and releasing entail sub stantially radial movement of the strapping mechanisms I68 and 180 relative to the coil which is accommodated in the mechanism illustrated by vertical movement of the upper strapping mechanism 168 by means of the fluid-pressure member 170 and swinging of the arms 174 mounting the strap mechanisms 180 relative to parts 172 achieved by the fluidpressure members I78. After the strapping operation has been completed and the strapping mechanisms 168 and 180 have been moved outwardly clear of the compacted strapped coil 182, the strapping assembly 150 may be retracted from carrier assembly 24 by actuation of the fluid-pressure member 160. Also, the compacting assembly 122 is withdrawn or retracted to the FIG. 5 position by actuation of the fluid-pressure member 142. Thereupon, the coil carrier assembly 24 and the coil carrier 56 may be swung to an unloading position as illustrated in dotted lines in FIG. 4 preparatory to repetition of the operation.

The device may be provided with suitable control means (not shown) for sequencing the operation of the device to achieve a rapid operating cycle. Also, safety mechanisms may be incorporated in the control means, for example. mechanisms to prevent swinging of the coil carrier assembly 24 during loading thereof and until the loading means 184 has moved clear of the apparatus. Also, the fluid-pressure systems may be so correlated with the control system as to permit the motor and pump of the device to run at no load while the hydraulic system is fully pressurized, as during the time that the straps are being advanced, tensioned and sealed. It will also be understood that automatic cycling is not essential, and that the device may be operated by manual controls in the desired sequence.

While the preferred embodiment of the invention has been illustrated and described, it will be understood that changes in the construction may be made within the scope of the appended claims without departing from the spirit of the invention.
